U.S. House Speaker Nancy Pelosi said on Thursday that U.S. President Donald Trump threw a temper tantrum at a meeting with Democratic congressional leaders a day earlier and she wished his family or staff would conduct “an intervention” with him for the good of the country.

In a second consecutive day of tough words about Trump by the Democratic Speaker of the House of Representatives, Pelosi accused Trump of obstruction of justice, which she said is an impeachable offence.

“Again, I pray for the president of the United States. I wish that his family, or his administration or his staff would have an intervention for the good of the country,” Pelosi told reporters.

On Wednesday, shortly before a previously scheduled meeting with Trump at the White House to discuss infrastructure investment legislation, Pelosi accused Trump of a “coverup” in regard to investigations related to Russia’s meddling in the 2016 U.S. elections.

Her remarks rankled Trump and prompted him to walk out of the infrastructure meeting after just three minutes, possibly sinking the legislation’s prospects.

Trump held an impromptu news conference Wednesday in the Rose Garden at the White House, saying it was impossible to work on such legislation as long as Democrats were continuing their “phoney” investigations of him.

At her weekly news conference on Thursday, Pelosi remained on the attack, repeating her contention from the previous day that Trump was incapable of working on complex legislative issues.

“I can only think that he wasn’t up to the task of figuring out the difficult choices of how to cover the cost of … the important infrastructure legislation that we had talked about three weeks before.”

Pelosi called Trump a “master of distraction.”

Pelosi ‘irresponsibile’: top Republican

While she raised the issue of obstruction, Pelosi also said House Democrats were not yet prepared to launch formal impeachment proceedings against Trump.

Both White House spokesperson Sarah Huckabee Sanders and White House senior adviser Kellyanne Conway have accused Pelosi of imperious behaviour in media interviews since Wednesday’s dust-up.

When asked about Conway’s comments by a reporter Thursday, Pelosi responded, “I’m not going to talk about her.”

Even though Trump has indicated he is not willing to engage in bipartisan work on legislation as long as House Democrats are investigating him, Pelosi and Senate Democratic Leader Chuck Schumer on Thursday challenged Republicans in Congress to leave the Republican president behind and continue working on legislation without him if he is unwilling to engage.

Lawmakers are trying to put the finishing touches on a long-delayed disaster aid bill.

Meanwhile, Republican and Democratic leaders in Congress want to strike a two-year deal on federal spending levels and raising the U.S. Treasury Department’s borrowing authority.

Both are needed to avert government shutdowns and a possible credit default later this year.

Kevin McCarthy, the top Republican in the House, said in his weekly address that Pelosi was “irresponsible” to make her “coverup” remark ahead of a meeting that had been weeks in the making.

McCarthy, from California, suggested that House members should not go on break for the upcoming Memorial Day weekend but stay to hammer out bipartisan legislation to “show the American public we can govern.”
